To all whom it may concern `Be it known that I,'BEN C. Hour, a citi ren of the United States, residingi at Spokane, in the county of Spokane an Improvements in Combined Harvesters, of which the following isa' specification.

This invention relates to combined har-l vcsters, and pertainsespecially to an automatic straw spreader therefor.

At present in combined harvestinsI and threshers, straw is 'strewn 'back of the ma-v chine in narrow rows and where the grain is even moderately heavy, or thc cut oi the harvester is wide, the roll of straw deposited on the ground is so thick as to intert'ere seriously with subsequent cultivation. The practice has vbeen to go over the field ina separate operation and dispose of the straw citherby scattering orzburningit. Scattering `is preferable to burning since the straw has some value as a fertlizeigif evenly and thinly spread, whereas burnin tends to injure the fertility of the soil. owever, the labor of scattering the straw is so gieat that man are forced to dispose of it by burning it. t is the object of this invention to autoniaticall scatter or spread the straw thinly an evenly over the ground in connection with cutting and threshing of the standing grain. This Iaccomplishbby Ycombining with the harvester and thresher scattering devices roperly ositioned and operated by lianism -o the thresher.

a combined harvester, as iswell known,

sacked in 'one operation, as the machine moves over the ground the straw and chai being delivered at the rear and the threshed State of Washington, have invented new and useful :and sacked grain discharged from time to time from the machine as the sacks are filled and seu'ed. l

' A represents the frame and housingV o a traveling harvesting and threshing machine supported on wheels 20. The usual header frame having its outer end` supportedxon a lrrain wheel 21 is shown at 22. The header rame carries a cut-ter bar 23 which cuts theI grain and causes it to fall on a drapcr 24 which conveys it in the well known manner to a threshing mechanism including a cylin der shown in dotted lines at 19, a separating screen 1,8 and a straw carrier 2 upon which the refuse straw and chaff, after the rain has been threshed, is delivered. In or er to separate the chaff from the straw so that the `chaff may be saved for feed, the straw carrier has slats set fairl wide apart, permitting the chaff to fall. t rough into the dump 4 beneath. From thc carrler 2 the straw is delivered to the straw scatterer, and distributed rearwardly behind the machine so that. it will be plowed under during the s. later plowing season.

This straw scatterer consists referably of two series of spreader arms and) claws 6, arranged on opposite sides of the central axis of the machine and mounted on vertical shafts 7 driven from. a horizontalshaft 8 by suitably beveled gearing 9.

The spreader arms are curved and bifurcated to form the claws 10,` and are bolted t0 Patented Oct. 22, 1918.

The two sets of spreaders revolvein 0ppm` site directions and are driven from the main" ower plant on the machine4 and vdirectly rom' the straw conveyor shaft 15, by a.V suitf,

able chain and sprocket mechanisml. `The frame extension 13 tor the spreader is supported by rearwardly' extend'in bracket arms 17 bolted to the main` fr amfo the thresher so that the scattering gevices may be quickly attached and dete at.

The formation of each Set of spreading elements is by means of apair of oppositely extending arms 6 on the hub 11 one pair beingl an at right angles thereto to form radial ,arms effective throughout a considerable depth. By the presence of the deiiector l2 al1 straw from the conveyer or carrier 2 is guided on to the scatterers and the divider '14 serves to lconfine the straw so as to permit the scatterers to act more positively thereon. The bifiircated ends 10 on the scattering` arms form tines, effective over a wider area and and pitching alargc capable of engaging3 amount of straw. y arranging the scat 4terers below the pla-ne of the conveyer or a straw spreader in connection therewith,
